Root-run gateways have $HOME=/root, which is on the MEDIA system-path
denylist, so the gateway silently dropped agent-generated deliverables
under /root (e.g. /root/work/proposal.docx) — the user got a 'here is
your file' reply with nothing attached.
_path_under_denied_prefix now treats the running user's own home as
deliverable: the home tree itself is no longer denied, while the
more-specific denied paths inside it (~/.ssh, ~/.aws, ~/.hermes/.env,
auth.json, config.yaml) stay blocked because they are separate denylist
entries. The exception only matches when the denied prefix IS $HOME, so
a non-root gateway still can't deliver another user's home.
Diagnosis, reproduction, and the failing-case analysis are from
@GodsBoy (#38108 / #38106). Implemented here as the minimal denylist
fix rather than a staging/copy subsystem.
